Browsing the App Store can be a bit overwhelming. Which apps are new? Which ones are good? Are the paid ones worth paying for, or do they have a free, lite version that will work well enough?

Well, if you stop interrogating me for a second, hypothetical App Store shopper, I can tell you about this thing we do here.

Every week, we highlight some of the most interesting new apps and collect them here for your consideration. This time, our picks include a self-improvement program that wants to save you time, a guide to how to properly brush your teeth, and a timer with a beat.

Here you go:

Better Every Time — Productivity — Free

The App Store is full of things to help you set goals and keep you accountable, usually by making everything visible to your friends so they can goad you into persevering. Better Every Time takes a different approach, offering no social media connectivity whatsoever. Instead, it turns your quest of betterment into a journey to the top of a mountain and leaves it to you to check in along the way. Doing so just takes a few seconds, leaving you free to improve yourself.

So it’s basically an app that doesn’t want you to use it too much, which is an interesting angle.

In these troubled economic times, we don’t really have the luxury of putting real coins into a jar every time we drop a bomb in front of Grandma. Luckily, we have Swear Jar, a virtual container you can drop change into so you can quantify your dirty mouth. You can use any denomination of change you want, and it’ll keep a running tab of your blue streak. It even has motion controls so that you can jingle the coins around.

Food labels can be scary places. Reading the ingredients of whatever you’ve just crammed into your gob can be confusing or even the worst decision you’ve made all day. I don’t know how to keep the stuff in your food from terrifying you, but for those perplexing moments, try Simple Additives. It’s an app that will tell you what those unpronounceable things in your snack do and also whether or not they’ve been linked to cancer or harmful side effects.

I don’t know if I’m really doing you a favor by pointing you toward this, though. Everything’s tasted like poison for like three hours now.

It’s important for people to learn proper tooth-brushing techniques, and not just because toothpaste and floss are way cheaper than root canals and fillings. Brushing is just an important part of fitting in with society because society is full of people who will notice if you have broccoli stuck in your teeth or if your breath smells like the inside of a garbage disposal.

MyTeeth is here to help with a selection of slightly creepy-looking children who will brush along with your kids — or you — to ensure that your chompers get nice and clean. Just don’t stare into their beady little eyes too long. I think I saw Cthulhu in there.

I’ve featured timers here before, but this is one you should definitely check out.

Humming Timing looks at other time-keeping apps and wonders why they have to be so quiet. Its solution: to make a countdown using music from your iPhone’s library. So for example, you’ll put your cake in the oven, set the app for 35 minutes, and it will craft an exactly 35-minute-long playlist from your tunes and tell you which song to listen for for the end.

It’s basically a timer you can dance to. If that’s something you’ve been looking for.
